Yuanfeng Netshield free website spam filter

Yuanfeng Netshield is the first cloud computing software in China that scans and filters content for website spam.

Our system currently has four high-speed intelligent scanning engines:
1. Digital fingerprint scanning engine: It collects a large amount of junk information, and the system extracts the digital fingerprint of this information according to a certain algorithm. It can quickly compare the information provided by users and make efficient and accurate judgments.
2. Heuristic scanning engine: A self-learning scanning method that can make appropriate real-time adjustments to the algorithm during the scanning process based on the content provided by the customer.
3. Statistical scanning engine: Based on the probabilistic statistical algorithm, it can infer whether the new information provided by the customer is spam based on existing information.
4. Lexical scanning engine: Scans all information based on existing lexicon, which can effectively block illegal, reactionary, and other information that hinders the harmonious development of the network.
In addition, we can currently scan information such as Trojans and viruses. Since the Trojan and virus databases are small, we can only identify a small number of Trojan viruses. We will continue to strengthen this in the future.
